STA Services Are Interrupted
The AC cannot be pinged from the STA.
- Obtain packets on the STA to check whether packets are sent out from the STA.
- Obtain packets on the AC to check whether ping packets reach the AC.
- If the STA sends out the packets but the AC does not receive them, check whether packets reach the AP. If the AP discards the packets, find out the reasons. If the AP also sends out the packets, the network between the AP and AC may be faulty.
- If the AC receives the packets, check whether the AC sends a ping response packet.
- If the AC sends a ping response packet, check whether the AP receives the ping response packet.
The STA cannot be pinged from the AC.
- Check whether the STA receives the ping packet.
- If not, check whether the ping packet reaches the AP. If the AP does not receive the ping packet, the network between the AP and AC is faulty. If the AP receives the ping packet, check why the AP does not send the packet to the STA.
- If the STA receives the ping packet, check whether the ping response packet reaches the AP. If the AP receives the packet and does not discard it, check whether the intermediate network is normal. If the AP discards the packet, find out the reasons.
